images of the survey lines and evidence collected while the columns are used to
record angles, distances, point names and descriptions of evidence. Field topics
are available with different types of rulings (columns and squares). The topics
usually contain water repellent paper so they can be used in inclement weather.
Because the topics are sewn and bound, the pages form a permanent record. Many
ield topics contain 60 or 80 pages, so records for many surveys can be kept in a
single topic. Sometimes loose leaf ield topics were used. In this case the pages
for a particular survey were often removed and kept in the folder with the remain-
der of the survey records. Surveyors must always create a table of contents in
each bound ield topic showing the page numbers for each of the surveys. When
a survey office has been in business for many years and it has accumulated a large
number of ield topics, it is necessary to have an index of the surveys and the ield
topic number and page corresponding to the survey.
Field topics serve as important and unique records of boundary surveys. For
many surveys, plans are recorded in a public recording system for the purpose
of memorializing the results of a boundary survey. However, plans often do not
show all of the information and evidence that was gathered during the field work.
Traditionally, this information was written into a ield topic. Where a public
agency, such as a local highway department, performed ield work, the ield topic
would sometimes be stored in a vault or other fireproof and secure location. These
